Former Jon & Kate Plus 8 star Collin Gosselin is sending a warning to his estranged mother, Kate, ahead of the release of his new memoir.
Collin and his seven siblings — twins Mady and Cara, 25, and fellow sextuplets Alexis, Hannah, Aaden, Leah and Joel — had their upbringing documented on the TLC reality series, which premiered in 2007. The series followed the large family as parents Jon and Kate navigated their 2009 divorce and ultimately parted ways.
